To round to the nearst thousands, you check the digit after the one in the thousands position (this means you check the digit in the hundreds position), if this digit is equal to or greater that 5 then you will add 1 to the thousands and all other digits will be zeroes, otherwise, you won't add anything and only change other digits to zeroes.
applying this here, you will find that the number in the hundreds position is 6 which is greater than 5,
therefore 8624 to the nearest thousands is 8700
Plug in 6 for a (since we are told a=6)
6+10=16 <---add
Answer 16
First to figure out the length of the side of the square you do the square root of 64 which is 8. now 8 × 4= 32
Answer:
c 1/2
Step-by-step explanation:
You are incorrect.
We are going from ABCDEFGH to A'B'C'D'E'F'G'H'. We are going from the large octagon to the small octagon. The scale factor of a dilation is the number you multiply the original lengths to get the lengths of the dilation.
![scale~factor = \dfrac{length~of~dimension~in~dilated~image}{length~of~corresponding~dimension~in~original~figure}](https://tex.z-dn.net/?f=scale~factor%20%3D%20%5Cdfrac%7Blength~of~dimension~in~dilated~image%7D%7Blength~of~corresponding~dimension~in~original~figure%7D)
Look at point (6, 0) which becomes (3, 0) in the dilation.
The distance from the origin to (6, 0) is 6 units.
The distance from the origin to (3, 0) is 3 units.
scale factor = dilated/original = 3/6 = 1/2
The scale factor of the dilation is 1/2.
Also look at segment AB whose length is 4. The length of segment A'B' is 2.
scale factor = dilated/original = 2/4 = 1/2
Answer: 1/2
